Never. I have seen only mine. Ever. And I’ve owned mine since September and have been curious about them long before that...
Bought mine in mid February. In Nassau County. Saw black one in Oceanside 2 days ago. Mine is white. Will keep on looking.Saw green clarity on Belt Parkway - Brooklyn, NY on 3-18 around 4pm, near Coney Island.
Sounds like you saw every member of an unicorn herd.Seven. I have seen 7 unicorns in my lifetime.
But never another Clarity.
